Electric power industry carbon emission right distributing method based on improved entropy weight method

Abstract

The invention provides an electric power industry carbon emission right distributing method based on an improved entropy weight method. Going deep into the electric power industry carbon emission process, in combination with the influences of discharge emission intensity, comprehensively considering the encouragement mechanism of clean energy power generation orientation and promoting the green and low-carbon development of the electric power industry, the carbon emission right distributing scheme is more reasonable. With the aid of the entropy definition and properties in the information theory, rules between all index relation properties are excavated, information entropies are introduced to serve as effective value indexes of all factors of the carbon emission right distribution, artificial subjective consciousness interference can be effectively avoided, the logic relation among all the indexes is well reflected, and the distribution result is more accurate and is closer to reality. By improving the calculating method of the index effective values, it can be avoided that small differences of entropies probably cause the multiplication of entropy weights and the inconsistency ofthe entropies and transmitted information, and the problem that corresponding entropy weight numerical values are not stable when the entropies of traditional entropy weights are close can be well solved.

Description

technical field [0001] The invention relates to the technical field of carbon emission rights allocation in the electric power industry, and more specifically, relates to a carbon emission right allocation method in the electric power industry based on an improved entropy weight method. Background technique [0002] The emission of greenhouse gases is one of the main factors leading to global warming. How to achieve low-carbon development has become a common goal of various industries. The "Kyoto Protocol" first proposed the concept of carbon emission trading, pointing out that CO2 emission rights can be like ordinary commodities Transactions are carried out in the same way, and the role of resource optimization allocation is fully utilized under the mechanism of total control-allowing transactions. However, CO2 has a strong public good attribute because its impact on the environment is global, which makes carbon trading different from other common commodity transactions, an...

Problems solved by technology

On the basis of the carbon emission characteristics of thermal power units, relevant scholars have proposed a multi-unit carbon emission rights allocation mechanism based on emission performance and equal emission micro-increase rate. However, this allocation mechanism only considers the type of power generation of thermal power units. The marketization model is not well considered

Some scholars combined the characteristics of the West-to-East power transmission of the South Power Grid, and allocated it based on the proportion of regional clean energy power generation connected to the grid, fully considering the impact of power generation emission intensity, which has a positive role in promoting low-carbon development. The transaction is in the initial stage, and the power generation structure is mainly based on thermal power. This plan has greatly dampened the enthusiasm of fossil energy power generation companies to participate in the market, and is not conducive to the development of the transaction

Some scholars have established a two-level allocation model of carbon emission rights based on regional comparison based on the distribution idea of ​​"two convergences". Carbon flow, distribution results are slightly extensive

In addition, some scholars have established a mathematical model of carbon and sulfur tracking based on network computing, which takes into account the amount of network loss allocation. The physical concept is clear, but the calculation process is relatively cumbersome, and it is not suitable for the allocation of carbon emission rights in complex large power grids.
